2. Kraft process - Wikipedia

   en.wikipedia.org/wiki/Kraft_process

   The kraft process involves treatment of wood chips with a hot mixture of water, sodium hydroxide (NaOH), and sodium sulfide (Na 2 S), known as white liquor, that breaks the bonds that link lignin, hemicellulose, and cellulose. The technology entails several steps, both mechanical and chemical. It is the dominant method for producing paper.

7. Dissolving pulp - Wikipedia

   en.wikipedia.org/wiki/Dissolving_pulp

   Dissolving pulp is made from the sulfite process or the kraft process with an acid prehydrolysis step to remove hemicelluloses. For the highest quality, it should be derived from fast-grown hardwoods with low non-cellulose content. [3] The sulfite process produces pulp with a cellulose content up to 92 percent.

8. Celluloid - Wikipedia

   en.wikipedia.org/wiki/Celluloid

   The first step is transforming raw cellulose into nitrocellulose by conducting a nitration reaction. This is achieved by exposing the cellulose fibers to an aqueous solution of nitric acid; the hydroxyl groups (-OH) will then be replaced with nitrate groups (-ONO 2) on the cellulose chain. The reaction can produce mixed products, depending on ...
